Background: The emergence and spread of multidrug-resistant organisms (MDROs) represent a threat to human and animal health.Objectives: To assess duration of Hockey Protective - Gloves - Senior carriage of MDROs in dogs and cats presented to veterinary clinics/hospitals in Switzerland.To estimate prevalence, duration of and risk factors for MDRO carriage in their owners and the occurrence of co-carriage in owner-pet pairs.Methods: Prospective, longitudinal, observational study.Nasal swabs and fecal samples were collected from 50 owners of dogs and cats presented to 3 large veterinary hospitals, 1 medium-sized clinic and 1 practice.
If pet or owner tested positive for a MDRO, follow-up samples were collected for up to 8 months.Methicillin-resistant (MR) Staphylococcus aureus, MR S.pseudintermedius, MR coagulase-negative staphylococci (MRCoNS), MR Macrococcus spp., cephalosporinase- and carbapenemase-producing (CP) Enterobacterales were isolated and further characterized by MALDI-TOF MS, microdilution, β-lactam resistance gene detection, REP/ERIC-PCR, multilocus sequence typing or whole-genome sequencing.Risk factors for MDRO carriage in owners were explored based on questionnaire-derived data.
Results: Five out of 50 owners carried 3rd generation cephalosporin-resistant Enterobacterales (3GC-R-Ent.), and 5/50 MRCoNS.In 3 dogs and 4 cats carriage of 3GC-R-Ent.persisted for up to 136 days after discharge (median 99 days, IQR 83 days, range 36–136 days), in two cats isolates were carbapenem-resistant.Owner-pet co-carriage was not observed.
No specific risk factors for MDRO carriage in owners were identified.Conclusions: After discharge from veterinary care, Bike Parts - BMX - Wheel Rims dogs and cats may carry 3GC-R-Ent.for prolonged time periods.Carriage of MDROs was common in owners, but pet-owner co-carriage of the same MDRO was not observed.
